The guides included with my pocket door didn't extend quite far enough to guide the door back into the pocket when it was completely closed. I made a version that was .444 wide at the base initially and tapered to the top, but it was a bit too thick for my needs. The .179 thick version worked perfectly for me. I tapered the edges so that the door would more naturally slide into them, which I consider an upgrade over the originals with a flat edge. I hope you get good use out of the design!
